Whenever possible, the same reference numbers will be used throughout the drawings to refer to the same or similar parts. Furthermore, although terms used in the present invention are possibly selected from some currently well-known ones, some terms are arbitrarily selected by the application in some cases in such a way that their meanings are explained in detail in the following description. Therefore, the present invention should be understood with the meanings of the corresponding terms selected by the application instead of the simple names of the terms. 'Recording medium' used in the present invention means all the means that can record data. For example, 'recording medium' includes all types of media such as an optical disk, a magnetic tape and the like regardless of. its recording systems. For convenience of explanation, an optical disc, and more particularly, a 'Blu-ray (BD)' disc is taken as a recording medium to explain the present invention. The prior art of the present invention can be applied to other recording media in the same way. FIGURE 1 is a diagram of a recording area structure of an optical disc according to an embodiment of the present invention, in which a recording area structure of a recordable BD is shown. With reference to FIGURE 1, an optical disk includes three parts divided into an input area, a data area and an output area. Specifically, the data area includes a user data area for recording the data of real users therein and a spare area for replacing a defective area within the user data area. The spare area includes an inner spare area (ISA) provided in an inner circumference of the data area and an outer spare area (OSA) provided in an outer circumference of the data area. In the previously configured optical disc structure shown in FIGURE 1, recording is performed in all areas within the data area by the allocation unit. Specifically, each allocation unit is subdivided into a plurality of recording units. For example, the present invention names the 'sector' of the recording unit. A total of 32 sectors are provided within each allocation unit. And, an AUN (address unit number) is given for each pair of sectors. Therefore, the total of 16 AUN addresses are recorded within each of the allocation units, so that the address location of each of the sectors can be confirmed from the recorded AUN. The confirmed sector address is called ¾PSN (physical sector number) '. The present invention relates to a method for recording data in the allocation unit and the data structure that configures the data to be recorded, which is explained in detail as follows. FIGURE 2 is a diagram for the conceptual understanding of a method for recording data in a recording medium according to the present invention. With reference to FIGURE 2, a method for configuring an ECC allocation unit 200 as a recorded data structure within an allocation unit is shown sequentially. First of all, the data that is recorded 10 includes user data 10a that is recorded and user control data 10b. Specifically, the user data 10a is provided from a control unit or computer 12 shown in FIGURE 5. And, the user control data 10b includes previously determined control information. The 4-byte error detection code (EDC) is added to the user data 10a to configure a data frame 20. The data frame 20 uses AUN (address unit number) to configure a randomized data frame constructed with 32 columns. Each of the columns of the randomized data frame 30 is rearranged to configure a data block 40 constructed with 304 columns * 216 rows. To provide error correction capability, the RS (Reed-Solomon) code is added to the data block 40 to configure an LDC 50 (long distance coding block). The LDC block 50 is interleaved to avoid the occurrence of error concentration, whereby an LDC assignment unit 60 constructed with 152 columns * 496 rows are configured. Meanwhile, the user control data 10b uses an address unit 100 that includes 16 AUN values and the control information for configuring an access block 70, whereby an optical recording / reproducing apparatus in FIG. 5 facilitates access to the data within the corresponding allocation unit. To provide error correction capability, the RS (Reed-Solomon) code is added to the access block 70 to configure a block 80 of BIS (burst indication subcode). Block 80 of BIS is interleaved to avoid the occurrence of error concentration, so that an allocation unit 90 of BIS constructed with 3 columns * 496 rows are configured. The LCD assignment unit 60 of 152 columns * 496 rows is divided into four LDC 220a of 38 columns * 496 rows each. And, the allocation unit 90 of BIS of 3 columns * 496 rows is divided into three BIS 200b of a column * 496 rows each. Finally, the LDC 200a and the BIS 200b are arranged in a sequence of LDC (200a)? BIS (200b) - > LDC (200a)? BIS (200b)? LDC (200a) -BIS (200b) ~ »LDC (200a) to configure ECC assignment unit 200 of 155 columns * 496 rows. After this, the synchronization information and the like is given to the ECC allocation unit 200 to be written to a specific allocation unit within the data area. FIGURE 3 shows a data structure of the address unit 100 that includes the 16 AUN values and the control information. With reference to FIGURE 3, the address unit 100 includes 16 address fields 100a indicating 16 AUN values within an allocation unit, respectively. Each of the address fields 100a are constructed with a total of 9 bytes including AUN address information of 4 bytes, a control information field 100b (label bits) indicating the attribute per recording unit of 1 byte , and a field 100c of error correction where parities of 4 bytes for the correction of errors are recorded in it. For convenience of explanation, each byte that configures the address field is represented by ¾AFx, and ', where AF means an address field. For example, the 4-byte AUN address information that configures a Svo address field between the 16 address fields 100a is represented by 'AF0, s ~ AF3iS'. The 1-byte control information field 100b is represented by, AFjS '. And, the 4-byte error correction field 100c is represented by ¾AF5, S ~ AF8, S '. FIGURE 4 shows the 16-byte data structure of ¾AF4, or ~ AF4ii5 'that configure the control information field 100b within each of the address fields, each information that configures the control information field 100b is explained in detail as follows. First of all, the 8 sequential bytes of 'AF4i0 ~ AF, 7' is used as Sai of status information (status label for sector I) indicating 32 attributes per sector as a recording unit within the allocation unit . For example, the present invention uses 4 bytes (F4 (or ~ AF4,3 ') among the 8 bytes to indicate 1 bit as each attribute information per sector.It is defined that 1Sai = 0b' means a sector without error that ensures data forces Sai = lb 'is defined as an erroneous sector that does not ensure data forces, and the rest of the 4 bytes (, AF4; 4 ~ AF4 &7') are left as an area However, it is apparent that the Sai state information can be used to indicate another meaning.When using the total of 8 bytes (, F4 / or ~ AF4 / 7 ') as status information, it is able to provide subdivided status information by assigning 2 bits to each of the 32 sectors within the allocation unit.When defining the status information, it is also capable of recording the status information in such a way that the allocation unit that exists within the User data area differs in definition of the allocation unit ion that exists within the spare area. In two sequential bytes of 1AF4i8 ~ AF i9 ', recorded is Recording_Date of data information indicating the date when the corresponding assignment unit was recorded. The data information Recording_Date is written in bit positions designated by a year-month-date sequence. In two sequential bytes of? AF) 10 ~ AF4 < 11 ', recorded is unique identification information of a recorder (RID: identification of the recorder) that wrote the corresponding assignment unit. The identification information is configured with rows of specific bits given only to each recorder. Finally, the location information of an original assignment unit before replacement is recorded in four sequential bytes of * AF4ji2 ~ AF (15 'if the corresponding allocation unit is a substitute assignment unit within the replacement area. if the corresponding allocation unit is not the substitute assignment unit within the replacement area, all are set to zero. The optical recording / reproducing apparatus in FIGURE 5 can precisely confirm the location of the original allocation unit that competes with the corresponding allocation unit from the location information ('AF4, i2 ~ AF4il5'), so that Compete with data restoration efficiently. FIGURE 5 shows a whole configuration of an optical recording / reproducing apparatus according to the present invention. First of all, 'optical recording / reproducing apparatus' in the present invention is used as a generic term for an entire system and equipment that records data in a recording medium such as an optical disc or reproduces data from a recording medium. In case of enabling an operation for recording data in a recording medium like the present invention, the apparatus is called 'recorder'. If used as a peripheral PC device, the device can be called a 'disk drive'.
With reference to FIGURE 5, an optical recording / reproducing apparatus according to the present invention basically includes a capturing unit 11 that reads data and handles information that includes the playback management file system information recorded within a disc. optical, a servo 14 that controls an operation of the pickup unit 11, a signal processing unit 13 that re-establishes a reproduction signal received from the pickup unit 11 at a specific signal value or modulates a signal that is recorded in a signal for recording an optical disk to be distributed in the pickup unit 11, a memory 15 temporarily storing the handling information and the like therein, and a microcomputer 16 which controls the operations of the pickup unit 11, the servo unit 14, the signal processing unit 13 and the memory 15. The configuration including the pickup unit 11, the servo unit 14, the signal processing unit 13, the memory 15 and the microcomputer 16 can be called the 'disk unit'. A decoder 17 provides a decoded signal, which is generated from the decoding of a signal reading of the optical disc according to a predefined format (e.g., MPEG decoder), to a final user. And, in order to perform a function for recording a signal on an optical disc, an encoder 18 converts an input signal into a specifically formatted signal, for example, an MPEG2 transport stream according to a control of the control unit 12 and it then provides the converted signal to the signal processing unit 13. The control unit 12 is in charge of a general control of the optical recording / reproduction apparatus. The control unit 12 receives a user command through interactions with a user and uses it to control the operations of the respective elements. A data recording method using the optical recording / reproducing apparatus previously configured in accordance with the present invention is explained in detail as follows. First of all, the control unit 12 distributes a location of a specific allocation unit to be recorded and the user data (10a in FIGURE 2) to be recorded in the corresponding allocation unit in the microcomputer 16 by the processing unit 13 of signals. In accordance with the control of the microcomputer 16, the signal processing unit 13 configures the final ECC allocation unit, as described in FIGURE 2, which includes the user data 10a, distributed from the control unit 12. The pickup unit 11 then records the ECC allocation unit configured in the previously determined allocation unit within the optical disk according to the control of the computer 16. Specifically, when configuring the data structure to be recorded in the allocation unit specific within the optical disk, the signal processing unit 13 generates the data structure for recording. In this case, the data structure includes the address unit in which a plurality of address fields per recording unit included in the corresponding allocation unit and the control information field indicating the attribute per recording unit is recorded. . And, each information that configures the control information field is identified by the byte unit and is randomized within the corresponding allocation unit to generate the data structure to be recorded. Accordingly, the present invention allows implementations of the data structure and the data recording method and apparatus that it uses, thus allowing a recording of reliable data. Industrial Applicability It will be apparent to those skilled in the art that various modifications and variations may be made in the present invention. Thus, it is intended that the present invention cover the modifications and variations of this invention with the proviso that they fall within the scope of the appended claims and their equivalents.
